This will subsequently require a reduction in operating temperatures and reduce the total power levels achievable by the core. However, the reduced mass will require reduced power for propulsion, resulting in a small, inexpensive nuclear electric spacecraft. This project will also demonstrate the operation of the ATEG conversion system through a series of lab bench tests by showing the improved characteristics of the new device. <\/p>\n<p>Video credit: NASA <\/p>\n<p class=\"MsoNormal\" style=\"margin: 5px;\">&nbsp;<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The Swarm-Probe Enabling ATEG Reactor, or SPEAR, is a nuclear electric propulsion spacecraft that uses a new, lightweight reactor moderator and advanced thermoelectric generators to greatly reduce overall core mass.<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[15,12,463],"tags":[822],"class_list":["post-3686","post","type-post","status-publish","format-standard","hentry","category-robotic-exploration","category-spacecraft-design","category-videos","tag-spear"],"_links":{"self":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts\/3686","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3686"}],"version-history":[{"count":1,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts\/3686\/revisions"}],"predecessor-version":[{"id":3687,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts\/3686\/revisions\/3687"}],"wp:attachment":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3686"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3686"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3686"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
